|In the Rock Tunnel’s basement area, behind some smashable rocks.
Starting from the Lavender Town Pokémon Center, head North.
Eventually you’ll enter Route 10. Pass the Pokémon Maniac NPC and follow the path as you make your way to the North part of the area.
By following the path, you’ll come across the entrance to Rock Tunnel.
You want to head inside, but it might be a good idea to have HM05 Flash if you want to make it easier to get the Coalossite.
As soon as you enter the cave just turn right.
Keep going right until you reach the right-most wall, then follow that path up.
After walking past two campers, you’ll see stairs. Take them to go down to the Rock Tunnel basement area.
As soon as you reach the bottom floor, you want to start going down.
Take the first right and continue going East, through the gaps in the walls. Start going up after walking through the second gap between the cave’s rocky walls.
You’ll see some smashable rocks here. Use Rock Smash on any rock and go East.
The Coalossite will be in the bottom-right corner of this space.
